• Filtration

Prior to the oxygenation process a high-tech 10" filter cartridge & capillary membranes.

The sintered carbon outer shell with a pore size of  0,5 mm removes sediments, turbidity, oxidized iron, larger microorganisms and almost all chlorine, bad tastes and odors, herbizides, pestizides, fungizides, insektizides, drug residuals (espec. steroid hormons) as well as lead.
The inner cartridge of capillary membranes has pores of only  0,15 mm  (absolute!).  Due to the fact that the size of the smallest bacteria is 0,3 mm, they obviously cannot pass the filter cartridge. 

The filtered water flows then through a pressure regulator (15) to the oxygenating chamber (7).
A check valve (5) prevents the oxygen gas from getting into the water supply line.

• Sauerstoff-Anreicherung

Inside the diiffusor (7) the filtered water and the oxygen gas mix together. The pressure inside the diffusor is approx.  3  bar.
Wenn no water is tapped then the system stays in balance and if all the components and connections are tight, no oxygen gas can escape. A check valve (6) prevents water from getting into the oxygen pressure tank.

4. Installation

·      Fix the base frame of the device verticaly to a wall or into a cabinet using the attached 4 screws.

·      Make a tight connection  between the water supply and filter housing dispenser inlet (1). This is usually a steel reinforced hose with connections 3/8" and a shot-off valve.

·      Fix the special (small flow) faucet (9) on the counter plate. A hole of 12 mm duameter has to be drilled.

·      Tighten the  faucet from bellow with a nut (wrench 15 mm). At the end of the same thread a special plastic connector must be screwed. Tichten this well but only by HAND. Using a wrench would crack the connector easily. 

·      Connect the faucet with the device outlet using the PTFE tube of 8/6 mm diameter. This connection should be short, but allow to take the device out for for service, if in a cabinet. It is recommended to put a little silicon-grease on the tube ebd and a stiffener sleeve inside the end for more secure connections. The tube end must be inserted into a socket 17 mm deep.  In case the outlet is closed by a stopper for transport, this must be removed before plugging the proper connection.   To remove a stopper or a tube press the collar of the plug towards the plug, then the stopper can be disconnected easily.  

·      In case the oxygen pressure tank (2) is not yet mounted, do this now. Insert the tank into the brackets and connect the outlet of the tank to the pressure reducer (3). Fasten the swivel nut well, but just by hand.
Do not open the valve of the oxygen tank yet!

5. Start-up

Put some container or bottle under the faucet. Open the faucet putting the handle in the front position .
Open the water supply and let several liters of water pass through the device, till no more air bubbles appear.  
Shut the faucet. The system must stay tight unter the water pressure. 

Open the valve on the oxygen pressure tank slowly. If the tank is full, the gauge (4) would indicate approx.  200 bar !
In a normal case no hissing sound indicating escaping gas can be heard. Should this although occur, shut the oxygen tank valve and wait till the oxygen lining remain pressureless. Then loosen the swivel nut by hand. Check the surface of the face of the outlet connection. No scratches, other demages or dirt are allowed. The surface must be free of fat (hands!). Then examine the black rubber O-ring in the pressure reducer (3) for obvious defects or dirt. Be aware that even very small particles may cause leakage of a gas at high pressure. If after connecting the the pressure reducer to the tank again the oxygen should escape, shut the tank valve and inform your service agent.

If everything is tight, open the faucet (12) and draw 3 to 5 liters of oxygenated water, then shut the faucet again

The device is now ready for tapping oxygenated water.


6. Exchange of the oxygen pressure tank

Close the tank valve. Close the water supply.

Open the faucet (12) and let the water drip out till the system becomes pressureless and the swivel nut of the pressure reducer (3) can be released  by hand. This may last several minutes but also half an hour. Don't aply violence.
Remove the oxygen tank from the device. Treat the tank, particularly the outlet connection with care.  
Protect the connecting thread and the face from defects.
The spare tank should be mounted as explained under items 4 & 5.
Don't forget to check the tank connection and the O-ring on the pressure reducer (3) before.

Safety  hints:

7. Exchange of filter cartridge

The filter cartridge (1) combining activated carbon & capillary membranes has high capacity, but should be replaced latest after 12 months ( the manufacturer recommends 6 months!)..

Take care that no unfiltered or poluted water touches the inner part of the new cartridge as well as the inner part of the filter housing's head. Wash your hands well after removing the used cartridge and cleaning the lower part of the filter housing. 

·         Remove the hood ·          Close the water supply ·          Prepare a cloth to pick up some water that may drip out from the filter housing ·          Loosen the lower part (sump) of the filter housing  from the fixed top using the special wrench (17), unscrewing anticlockwise (seen from bellow). In case it is difficult to loosen the sump, remove the water supply connection on the filterhousing's inlet (using a wrench 19 mm), let the remaining pressure release. Fix the connection again. The cartridge may pinch in the top and thus it is necessary to move it a little to get it out more easily. Sometimes the plastic collar remains in the top and must be removed by means of pliers.
·          Remove the dirty cartridge and water from the sump. ·          Clean the sump inside well ·          Check the O-ring in the sump . If it is too dry, rub it a little with vaseline or silicon-fat. The ring must be distributed regularly in the groove. ·          Insert the new cartridge into the sump with its OUTLET up.  Take care that the black rubber gasket at the bottom of the cartridge doesn't fall out. Screw the sump to the top again using the wrench (17). Fasten it well but with some feeling! ·          Open the water supply. The system, particularly the filter housing, must stay tight under the water pressure. ·          Wash your hands carefully after exchaning the filter cartreidge, as you have contact with bacteria. ·          Open the faucet (12) and draw 3 to 5 liters water.          Caution:  It may last several minutes till the normal flow of 2 liters / minute is achieved. The fine pores in the capillary membranes must get wet first. ·        Fix the hood again.

8. When the device is not used for a longer period

For security reasons close the water supply and the oxygen tank valve.
Do not drain the device completely, particularly the diffusor must remain wet.

 

9. Warranty

The warranty period lasts 12 months. It begins at the moment of delivery, which is indicated on the invoice or delivery note.
The warranty concerns defects that occur with respect to material or manufacturing faults. The warranty will be denied, if the defects refer to inappropriate operation, ignoring the instruction manual or to intervention of a third party.
